In industrial ventilation and air pollution control, the ducting system that transports corrosive exhaust gases from source to treatment equipment is often the most overlooked component — yet it is frequently the first to fail. When a duct corrodes, cracks, or leaks, the entire waste gas treatment train is compromised: scrubbers lose their feed, monitoring…
The global industrial landscape is entering a pivotal regulatory era. As 2026 unfolds, environmental agencies across every major economic bloc are implementing sweeping new frameworks governing industrial air emissions and waste gas handling. In China, the Ministry of Ecology and Environment and the State Administration for Market Regulation jointly issued the revised Ambient Air Quality…
In the construction of modern global industrial infrastructure, choosing the appropriate ventilation medium is a crucial decision. This not only affects initial capital expenditure but also directly determines the operational safety and efficiency of the entire facility. For professionals specializing in exhaust gas treatment equipment , the choices typically narrow down to four main materials:…
In the rapidly evolving landscape of global industrial manufacturing, chemical processing, and commercial HVAC, the demand for reliable exhaust gas treatment equipment has never been higher. At the heart of these critical ventilation networks is a specialized thermoplastic conduit engineered to handle the most unforgiving environments. Unlike conventional metal ductwork, which rapidly degrades when exposed…
In industrial and commercial buildings, air ducts are a key component in the delivery and removal of air. PP plastic air duct and galvanized air duct are two common air duct materials, each with unique characteristics and advantages. This article will discuss the differences between PP plastic air ducts and galvanized air ducts in detail,…
Polypropylene (PP) is a thermoplastic material with excellent chemical resistance and good physical properties. Due to its light weight, high strength and high temperature resistance, it is often used in the manufacture of ventilation ducts. Polypropylene ventilation ducts offer many advantages over other materials such as steel or aluminum, which make them ideal for a…
PP pipe extrusion molding process characteristics As a generation of plastic ducts, PP ducts have a relatively high market share in the early 21st century. However, with the innovation and development of technology, PP ducts have been gradually eliminated by the market. As a third-generation product, PPR ducts add about 5-10% of PE materials in the production process…
Features of PP ductwork: PP ductwork is characterized by no corrosion, wear resistance, no scaling, vibration and noise reduction, anti-freeze cracking, anti-condensation, less heat loss, simple installation and long service life. Classification of PP pipes: 1.FRPP (corrosion resistance, high temperature resistance, high pressure resistance, hygienic non-toxic, recyclable, suitable for corrosive liquid transportation (such as acid-base…
Commonly used duct materials and their selection: 1. Thin steel plate Thin steel plate is the main material for the production of ventilation pipes and components, and is generally commonly used for ordinary thin steel plates and galvanized steel plates. Specifications are expressed in terms of short side, long side and thickness, and the thickness of…
The ventilation design of the laboratory is different from the ventilation design requirements of the comfort air conditioning system. The main purpose of laboratory ventilation is to provide a safe and comfortable experimental environment and reduce the exposure of the experimental personnel to the harmful air environment. Solve the physical health and labor protection of…
